 |

I have bchachefs as root fs with compression and compile /var/tmp/portage on tmpfs.
Some packages fails to install with:
| Code: | Failed to copy file: _parsed_options=Namespace(group=-1, owner=-1, mode=420, preserve_timestamps=False), source=b'/var/tmp/portage/app-misc/screen-4.9.1-r1/files/screenrc', dest_dir=b'/var/tmp/portage/app-misc/screen-4.9.1-r1/image/etc'
Traceback (most recent call last):
File "/usr/lib/portage/python3.12/doins.py", line 200, in run
movefile._copyxattr(source, dest, exclude=self._xattr_exclude)
File "/usr/lib/python3.12/site-packages/portage/util/movefile.py", line 99, in _copyxattr
raise OperationNotSupported(
portage.exception.OperationNotSupported: Filesystem containing file '/var/tmp/portage/app-misc/screen-4.9.1-r1/image/etc/screenrc' does not support extended attribute 'bcachefs_effective.compression' |
When I umount tmpfs it works well.

I can only offer guesses, but | Code: | | portage.exception.OperationNotSupported: Filesystem containing file '/var/tmp/portage/app-misc/screen-4.9.1-r1/image/etc/screenrc' does not support extended attribute 'bcachefs_effective.compression' |
your tmpfs does not support one of your bcachefs' attributes. Why portage is trying to set that attribute when copying from tmpfs to tmpfs is beyond me.

Because now you are writing to bcachefs. |

It's not from tmpfs to tmpfs, it's from bcachefs to tmpfs, the file it's copying is: /var/tmp/portage/app-misc/screen-4.9.1-r1/files/screenrc
And "files/" is going to be a symlink to /var/db/repos/gentoo/app-misc/screen/files.
That aside, haven't tried much but I can't reproduce in my bchacefs VM (test VM I happened to try bcachefs for rootfs in before) if I switch portage's tmpdir to use tmpfs as-is, probably need to set the xattr (I do have compression enabled but filesystem-wide rather than per-directory/file, don't know bcachefs well but assume the latter uses xattrs).
Edit: Presumably, that would solve this https://github.com/gentoo/portage/pull/1346 (pointed out by sam on irc) |

Note that setting
| Code: |
PORTAGE_XATTR_EXCLUDE="${PORTAGE_XATTR_EXCLUDE} bachefs.* bcachefs_effective.*"
|
in /etc/portage/make.conf should also fix this, even without the changes of the PR applied. |
